'shown in Fig. lxwhere thelstamp is .represented by "ath'ick line 6.'

In the 'form ofthe inventionshown inthe drawings, theguide ".'is-inade'liollovv at one end and `furnished With' an. aperture for the air currentnasindieated at 8. `pipe y9 is arranged to communicateivithithehollow portionf8and `is .attached to arotarypuinp or the like. (notI shown).

ylie'terring to Fig. 3, it @vill loe .observed ythat* the v aiir. current' indicated by 10; travels `from the .guide 7 across;theloecfly ofthemachine andimpinges upon the guidell Where it is deflected 1upwardly on totheunderside of thefree end of Vthe over hanging-,portion or portions of the stamp to support the same in a substantially horizontal position until the packet is moved into engagement with mechanism which folds the free end or ends of the stamp downwardly around the end or ends of the packet. By this arrangement it is possible to vary the distance between the guides 7 and 11 so as to ena-ble the machine to deal with packets of varying width without in any way affecting the position or arrangement of the upwardly directed air current relatively to each size of packet. The necessary adjustment may be effected by moving either or both of the guides 7 and 11 away from the center of the bed, but it is preferable to move the guide 7 only when the necessary adjustment is small. Regardless of the degree of adjustment of the guide 7 the air current will be directed beneath this guide and will be deflected upwardly upon striking the guide 11 so that the operation of the current of air is not affected by the size of the packet which is being operated upon.

In the machine shown in Fig. 1, the packet is removed from the vconveyor by a pair of rotary wheels 12 which feed the same beneath a vertical magazine 13, the latter including a plurality of brushes having inwardly extending bristles 13 for smoothing down the stamps and guiding the packets.

A reciprocating table 14' (Fig. 2) is adapted to lift the packet into the magazine so that the free ends of the stamp are pressed downwardly upon the packet, and asV the reciprocating table falls a cam operated tucker tucks the projecting end of the stamp beneath the leading edge of the packet. The table 14 slides in a guide 25 formed in the frame of the machine and is reciprocated vertically by a bell crank lever 26 operated by a cam 27. The tucker 28 for tucking the leading projecting end of the stamp is carried on a lever pivoted to the frame at 29 and operated by a cam 30.

The tucker 28 is pivoted to the lever at 31 and one end is pulled downwardly by a spring 32 so that the working end bears against a metal plate 33. As the cam 30 causes the tucker to move in and out beneath the packet, the spring 32 keeps the tucker in Contact with the plate 33 so that the working edge of the tucker moves horizontally. The next succeeding packet passing into the magazine folds the remaining projecting portion of the stamp beneath the packet.

It will be understood that various modifications may be made without departing from the spirit of the invention; for instance, a series of holes 9a communicating with the pipe 9 as shown in Figure 5 may be drilled in the bed of the machine beneath the path of the band or stamp and air blown through these holes in a verticalv direction. Such an arrangement is illustrated in Figure 5 of the drawings in which the air conduit 9 communicates with the passage 9l drilled in the bed of the machine, this passage serving to direct the air upwardly against the projection portion of the gummed stamp or label as indicated.

Thus it will be seen that according to the present invention there is provided means which ensures that the free end of the overhanging portion of a stamp is supported during the transit of the packet carrying the same along the bed of the machine prior to the packet being moved into the vertical stacker where the free end or ends of the stamp are folded downwardly and around the packet.

What I claim as my invention and desire to secure by Letters Patent is 1. A machine for applying bands, stamps or the like to packets which comprises means for applying adhesive to at least one side of the band, stamp or the like, means for applying the said band, stamp or the like to one side of a packet, a continuous conveyor for moving the packets into contact with the stamp applying means and means for supporting the overhanging gummed underside of the band, stamp or the like during the movement of the packet by said conveyor and prior to the same being folded around the end of the packet. i

2. The machine described in claim 1 in which said last'named means includes a device for directing a current of air upon the overhanging gummed underside of the band, stamp, or the like to support the same.

3. In apparatus of the class described, the combination with means for applying a gummed band to one face of a packet with a portion of the band extending outwardly of the said face, of means for folding the outwardly extending portion of the band across the adjacent face of the packet, a conveyor for transferring the packet from the zone of operation of said first named means to the zone of operation of said second named means, and means for supporting the outwardly eX- tending portion of the band while the packet is being transferred by the conveyor.

4. In apparatus of the class described, the combination with means for applying a gummed band to one face of a packet with a portion of the band extending outwardly of the said face, of means for folding the outwardly extending portion of the band across the adjacent face of the packet, a conveyor for transferring the packet from the zone of operation of said rst named means to the zone of operation of said second named means, and means for supporting the outwardly extending portion of the band while the packet is being transferred by the conveyor, said last named means acting to establish a dierent air pressure above and below the outwardly extending portion of the band.

5. In apparatus of the class described, the combination with means for applying a gummed band to one face of a packet with a portion of the band extending outwardly of the saidk face, of means for folding the outwardly extending portion of the band across the adjacent face of the packet,la conveyor. for transferring the packet from the zone of operation of said first named means to thezone 1o of operation of said second named means, and

means for supporting the outwardly extending portion ofthe band while the packet is being transferred by the conveyor, said last named means serving to direct a current of air against the inner gummed side of the outwardly extending portion of the band.

6. In apparatus of the class described, the

combination of a conveyor for receiving` and transferring packets, `of means for applying gummed bands to the packets with one end of the band extending outwardly of the packet,

means for folding the outwardly extending band about the packet, said rst and second named means acting at points spaced with respect to the direction of movement of the conveyor, guides disposed laterally `of the conveyor to retain the packets thereon, one of said guides being movable to vary the-spacing therebetween to accommodate packets of different widths, and means actingin conjunction with said guides and independently of the spacing therebetween to support the outwardly extending bandends prior to the folding operation. Y 7. In apparatus of the class described, the

combination of a conveyor for receiving and transferring packets, of means for applying gummed bands to the packets with one end of the band extending outwardly of thev packet, means for folding the outwardly extending band about the packet, said rst andy second named means acting at points spaced with respect to the direction of movement of the conveyor, guides disposed laterally of the conveyor to retain the packets thereon, one of said guides being movable to vary the spacing therebetween to accommodate packets of different widths, and means acting in conjunction with said guides and independently of the spacing therebetween to support the outwardly extending band ends prior to the folding operation, said last named means comprising a device for introducing air under pressure through one of said guides and into the space between said guides.

In testimony whereof I hereunto afix my signature.
